The Federal Stafford Loan has a fixed interest rate of 6.8% and the Federal PLUS loan has a fixed rate of 7.9%. This loan calculator also assumes that the loan will be repaid in equal monthly installments through standard loan amortization (i.e., standard or extended loan repayment).
The heart pumps oxygenated blood to the body and deoxygenated blood to the lungs. In the human heart there is one atrium and one ventricle for each circulation, and with both a systemic and a pulmonary circulation there are four chambers in total: left atrium, left ventricle, right atrium and right ventricle.he circulatory system of the lungs is the portion of the cardiovascular system in which oxygen-depleted blood is pumped away from the heart, via the pulmonary artery, to the lungs and returned, oxygenated, to the heart via the pulmonary vein.
In systemic circulation, the oxygenated blood is pumped into the muscles and the organs of the body through the arteries by the left ventricle. The nutrients and gases are exchanged at the capillaries. Then the blood enters the veins filled with cellular waste and carbon dioxide. This deoxygenated blood is then taken to the right atrium by the veins. The veins are blood vessels which carry the deoxygenated blood back to heart from the body tissues in our circulatory system.
